2010-10-21BKL: introduce CONFIG_BKL.Arnd Bergmann4-1/+4
With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2010-10-15llseek: automatically add .llseek fopArnd Bergmann24-1/+30
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-09-29pcmcia: remove obsolete and wrong commentsDominik Brodowski8-414/+0
What's worse than no comment? A wrong comment. Several PCMCIA device drivers contained the same comments, which were based on how the PCMCIA subsystem worked in the old days of 2.4., and which were originally part of a "dummy_cs" driver. These comments no longer matched at all what is happening now, and therefore should be removed.

As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

In order to support multiple ST platform devices, a new symbol 'st_get_plat_device' earlier needed to be exported by the arch/XX/brd-XX.c file which intends to add the ST platform device. On removing this dependency, now inside ST driver maintain the array of ST platform devices that would be registered. As of now let id=0, as and when we end up having such platforms where mutliple ST devices can exist, id would come from protocol drivers (BT, FM and GPS) as to on which platform device they want to register to.

2010-09-20Staging: vt6655: fix buffer overflowDan Carpenter1-3/+8
"param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function.

2010-09-20Revert: "Staging: batman-adv: Adding netfilter-bridge hooks"Sven Eckelmann2-19/+2
This reverts commit 96d592ed599434d2d5f339a1d282871bc6377d2c. The netfilter hook seems to be misused and may leak skbs in situations when NF_HOOK returns NF_STOLEN. It may not filter everything as expected. Also the ethernet bridge tables are not yet capable to understand batman-adv packet correctly. It was only added for testing purposes and can be removed again.

Increased storvsc ringbuffer and max_io_requests. This now more closely mimics the numbers on Hyper-V. And will allow more IO requests to take place for the SCSI driver. Max_IO is set to double from what it was before, Hyper-V allows it and we have had appliance builder requests to see if it was a problem to increase the number. Ringbuffer size for storvsc is now increased because I have seen A few buffer problems on extremely busy systems. They were Set pretty low before. And since max_io_requests is increased I Really needed to increase the buffer as well.

Checked builds of Windows are used internally and given to external system integrators at times. They are builds that for example that all elements in a structure follow the definition of that Structure. The bug this fixed was for a field that we did not fill in at all (Because we do Not use it on the Linux side), and the checked build of windows gives errors on it internally to the Windows logs.

2010-09-03staging: hv: Fix missing functions for net_device_opsHaiyang Zhang1-0/+3
Fix missing functions for net_device_ops. It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27, the default functions for Ethernet, like eth_change_mtu(), were assigned by ether_setup(). But in 2.6.32, these function pointers moved to net_device_ops structure and no longer be assigned in ether_setup(). So we need to set these functions in our driver code. It will ensure the MTU won't be set beyond 1500. Otherwise, this can cause an error on the server side, because the HyperV linux driver doesn't support jumbo frame yet.

2010-08-23Staging: batman-adv: Don't write in not allocated packet_buffSven Eckelmann1-0/+4
Each net_device in a system will automatically managed as a possible batman_if and holds different informations like a buffer with a prepared originator messages. To reduce the memory usage, the packet_buff will only be allocated when the interface is really added/enabled for batman-adv. The function to update the hw address information inside the packet_buff just assumes that the packet_buff is always initialised and thus the kernel will just oops when we try to change the hw address of a not already fully enabled interface. We must always check if the packet_buff is allocated before we try to change information inside of it.

2010-08-23Staging: batman-adv: Don't use net_dev after dev_putSven Eckelmann1-5/+6
dev_put allows a device to be freed when all its references are dropped. After that we are not allowed to access that information anymore. Access to the data structure of a net_device must be surrounded a dev_hold and ended using dev_put. batman-adv adds a device to its own management structure in hardif_add_interface and will release it in hardif_remove_interface. Thus it must hold a reference all the time between those functions to prevent any access to the already released net_device structure.

We try to get all events for all net_devices to be able to add special sysfs folders for the batman-adv configuration. This also includes such events like NETDEV_POST_INIT which has no valid kobject according to v2.6.32-rc3-13-g7ffbe3f. This would create an oops in that situation. It is enough to create the batman_if only on NETDEV_REGISTER events because we will also receive those events for devices which already existed when we registered the notifier call.

If a batman icmp packet had to be routed over a secondary interface at the first hop, the mac address of that secondary interface would be written in the 'orig' field of the icmp packet. A node which is more than one hop away is not aware of the mac address because secondary interfaces are not flooded through the whole mesh and therefore can't send a reply. This patch always sends the mac address of the primary interface in the 'orig' field of the icmp packet.
